Kyiv is 2.5 hours behind Colombo

Best overlap: 10:30 AM to 6:30 PM in Colombo is 8:00 AM to 4:00 PM in Kyiv.

Your window to reach both cities is 10:30 AM to 6:30 PM in Colombo, which converts to 8:00 AM to 4:00 PM in Kyiv. An 8-hour overlap gives you real choice here — early or late in the window both work comfortably. A quick caveat — Kyiv's clocks move for daylight saving and Colombo's don't, so the times here are right for only part of the year.
